Hypoglycaemia management with a hypercaloric supplementation in neonatal puppies delivered by caesarean section.

There is a high perinatal mortality rate in dogs, estimated at 20%, and one of the leading causes of this rate is hypoglycaemia. Therefore, we aimed to evaluate the efficacy of a hypercaloric supplement containing vitamins and amino acids in newborn puppies presenting hypoglycaemia at birth. Ninety-nine pups were divided into four groups: normoglycaemic caesarean section (NORMOCS), hypoglycaemic caesarean section supplemented with the hypercaloric (SUPLCS), hypoglycaemic caesarean section supplemented with glucose (GLICCS) and eutocic delivery (EUT). We evaluated the following parameters glycaemia, Apgar score, neurological reflexes and rectal temperature of neonates at the following moments 5 min (M5), 30 min (M30) and 60 min (M60) after birth. Brachycephalic dogs were 73.3% (22/30) of caesarean sections (c-sections). The puppy's average glycaemia represented about 90% of the maternal glycaemia, while 15.1% (14/99) of the neonates had hypoglycaemia (<90 mg/dL) at M0 and 46.5% (44/99) at M60. Only four neonates had glycaemia below 40 mg/dL at M30 but without showing any clinical signs. The puppy's fasting while waiting for the intraoperative period and the dam's anaesthetic recovery was considered risk factors for hypoglycaemia. There was no difference in mean blood glucose levels or vitality parameters among puppies from the SUPLCS and GLICCS. In conclusion, the hypercaloric supplement can be used as a replacement for glucose in hypoglycaemic puppies and it can also bring nutritional benefits for the puppy. The prepartum glycaemia of the dam is an important parameter to be measured, and the appropriate management of it reduces the chances of the puppies being born with hypoglycaemia.

Two Types of Management for the Noninvasive Treatment of Pectus Excavatum in Neonatal Puppies-Case Reports.

Pectus excavatum is a deformity of the thorax characterized by ventrodorsal narrowing of the sternum bone and costal cartilages, which can lead to compression and cardiopulmonary alterations in dogs, presenting a high prevalence in brachycephalic breeds. The aim of this report was to describe two types of management for the noninvasive treatment of pectus excavatum in newborn puppies of the breeds French Bulldog and American Bully. The puppies presented dyspnea, cyanosis and substernal retraction during inspiration. The diagnosis was performed by physical examination and confirmed by chest X-ray. Two types of splints were performed (a circular splint with plastic pipe and a paper box splint on the chest), aiming at thoracic lateral compression and frontal chest remodeling. The management was effective for the conservative treatment of mild-grade pectus excavatum, resulting in the repositioning of the thorax and improvement of the respiratory pattern.
